Interoperability

between GPS and JRANS

ITOCHU Corporation

NEC TOSHIBA Space Systems, Ltd.


Slide2 l.jpg

Interoperability between GPS and JRANS

JRANS will comply with “ Principles for Cooperation”.

・No Direct fees

・Open market

・Open signal structure

・Protection of the current radio navigation spectrum

・Use GPS standards

JRANSwill provide SIS similar to GPS L1 SPS

signal . JRANS system time will be steered for

UTC Japan.

・Interoperability for future GPS systems

JRANS SIS will be compatible with GPS civil

signal in L2 and L5.

・Recognition of international security

JRANS Interoperability

  • Validate JRANS and GPS performance based on GPS standards

  • Improve individual system through data and information interchange

  • Identify possible future improvements

  • US-Japan Cooperation is required for JRANS interoperability

  • with GPS L2 civil signal and L5 civil signal.

  • Not only interoperability with GPS but also interoperability with

  • SBAS should be considered in JRANS conceptual design.

Objective of interoperability
